Today is William Shatner’s birthday, and Hulu is making every episode from every Star Trek series available to watch for free until the end of the month. Resistance is futile. Almost as futile as controlling a population of tribbles.

We’re polling folks to find out which episode they’d like featured on the home page this weekend, and later today, iconic characters will face off in March Madness-style brackets, with Trek fans voting for their favorites. Check out Hulu’s Tumblr for more details.

Things will get heated. Friends may turn on each other.

But hopefully it won’t come to that. Check out every Star Trek episode here.
